The "Vampire Diaries" actress dropped the music video for her latest single, "1991," and we get to go to the ultimate '90s-themed house party, complete with some of our favorite trends from the decade -- from cut-off jean shorts to colorful leather jackets to FUBU bucket hats and mesh tops.

As the video unfolds, a guy is trying to get Kat's attention but all she wants to do is dance, and who can blame her, when the track sounds like a mix of TLC, Paula Abdul and Aaliyah? Graham eventually has a full-on old-school dance-off, before getting all Lisa "Left Eye" Lopes on us and dropping a rap verse that references Brandy and Monica's '90s smash "The Boy Is Mine."

If you're "old-school lovin'" this song, then get ready, because Kat -- who's putting out her next record on her own after leaving Interscope Records over lack of creative control -- promises that the 1990s will be a prominent theme throughout her entire album.

“My biggest peeve and worry -- I didn’t want people to think, ‘Oh, it’s so kitschy, contrived,'” she recently told MTV News. “No, I produced a record. I wrote the f--king record. I’m putting it out on my label. I’m doing it my way. The whole album is ’90s-inspired.”
